A storage electric sealer comprises a casing, a sealing module, a spring switch, a support cover, a press bar, and a sliding plate. The casing and the sealing module are arranged on the casing. The support cover includes at least two containing grooves. The press bar provided with a sliding chute is pivotally connected with the pivoting holder of the casing. The sliding plate is provided with a heat insulation block and at least a stopper, both lateral side of the sliding plate being connected with the sliding chute of the press bar in a sliding manner. Wherein, the sliding plate is located at a closed position in storage state, so that the stopper is accommodated in the containing groove of the support cover. As such, the storage electric sealer can be transformed into a storage state by a modified sliding mechanism to reduce the volume and damage rate effectively.

Storage electric sealer

A rechargeable sealer with storage function includes a casing, an electric heating module, a circuit board, a supporting base, a press bar, a spring-back mechanism, and a sliding plate. The casing is provided with an accommodating chamber, in which are provided with a fore contact element and a rear contact element. A rechargeable battery is positioned in and between the fore contact element and the rear contact element. The circuit board, provided with an external slot, is disposed in the accommodating chamber, featured in charging the rechargeable battery. The press bar is provided with a sliding slot, and is pivotally connected with the pivoting shaft of the supporting base, served as a pressing structure corresponding to the casing.

A main shaft structure of a tool machine includes a base, a worktable, a motor fixing seat, a cutter seat, and a cutter wheel unit. The worktable is mounted on the base. The motor fixing seat is connected to one side of the base, and another side is connected with the cutter seat. Two ends of the cutter seat respectively have bearing recesses and first positioning portions close to the bearing recesses. The cutter wheel unit is coupled to the cutter seat. Two ends of the cutter wheel unit are provided with bearing seats which are placed into the bearing recesses. The bearing seats have second positioning portions to connect with the first positioning portions, so that the cutter wheel unit can be detached from the cutter seat quickly.

An abrasive apparatus of a sander is provided. The abrasive apparatus is disposed above a worktable of the sander and includes a base and a lift unit. At least one abrasive wheel is provided in the base. The base has a top formed with at least one slot. The lift unit is disposed on the abrasive wheel to bring the abrasive wheel to move up so that an abrasive surface of the abrasive wheel passes through the slot of the base and protrudes from the base for the top of the base to sand the side of a workpiece. The cutting width of the sander can be extended to enhance the use of the sander, so the manufacturing process can be shortened to increase the production efficiency.

A hand-held electric sealer with a detachable sealing module includes a casing, a sealing module, and a press bar. The casing includes, among others, a front contact holder which is provided with an engagement hole. The sealing module includes, among others, a lower cover from underside of which extended an engagement piece. The engagement piece of the sealing module can be engaged with the engagement hole of the casing, such that the sealing module can be conveniently attached to, or detached from, the casing, and that replacement of a damaged sealing module can be readily achieved. In addition, for the sealing module dual heating wires may also be employed so as to obtain a desirable sealing effect to plastic bags.

Hand-held electric sealer with detachable sealing module

A hand-held electric sealer with dual heads includes a seat, a sealing module, a press cover, a supporting casing, and a battery cover. The seat has a central engaging rod and a first replacement element. The sealing module can be attached to, or detached from, the seat. The press cover includes a central engaging piece, a heat insulation block, and a second replacement element. Through engagement of the central engaging piece with the central engaging rod, the press cover can be selectively swung to press the heat insulation block against the sealing module, or to press the second replacement element against the first replacement element. The first replacement element and the second replacement element can be substituted with an appropriate module element upon demand on various functions.

Hand-held electric sealer with dual heads

A hand-held electric sealer having a detachable sealing module, comprises a casing having a module chamber located at the front end of the casing and a battery chamber beside the module chamber, a sealing module unitarily attached to or detached from the module chamber, and a press bar pivotally fixed at the rear end of the casing. Also disclosed is a detachable sealing module for use with the hand-held electric sealer, comprising a module cover plate and a module seat plate which form an accommodating space for receiving a heating mechanism, where the top portion of the heating mechanism protrudes from the module cover plate upon being biased by a spring secured in the module seat plate.
