Abstract: A hydraulic brake caliper piston/plunger tool includes a handle, a barrel with rear and front tubes, and a shaft. The handle is provided therein with a fluid reservoir and a fluid chamber, and pivotally connected with an operation lever having a plunger inserted into the fluid chamber. The shaft is attached with a piston and fitted through the rear tube, the barrel and the front tube. A return spring is fitted around the shaft in a central hole of the barrel, between the piston and the front tube. A front end of the shaft is adapted to be fitted with an accessory for a disc brake. A rear end of the shaft is adapted to be connected with a turning tool. In use, alternately depressing and releasing the operation lever enables fluid to enter the central hole of the barrel to have the piston together with the shaft moved forward.

Abstract: A mold tool generally includes a base, a die assembly, a tightening element, a threaded element, and at least one shaping cap. The base defines a cutout, a first threaded hole opposite to the cutout, and a second threaded hole. The die assembly, composed of a first module and a second module, can be inserted into a receiving space of the base. The tightening element can be screwed into the second threaded hole of the base to fix the die assembly in place. The threaded element can be screwed into the first threaded hole of the base. The shaping cap can be fitted at one end of the threaded element. The die assembly defines channels of various diameters each for holding a tube of a specific diameter. The shaping cap can urge one end of a tube held in the die assembly to form a specific type of flare.

Abstract: A switch with sounds includes a switch body provided therein with a recording device and a time controller. In using, a piece of sounds or music a user likes is recorded beforehand by the recording device, and then the length of time for sending forth the sounds or the music is preset by the time controller. When the switch body is turned on, the recording device will be started to send out the sounds or the music recorded in advance, and the sounds or the music will not stop until the time preset on the time controller, able to make a user relaxed and happy when turning on the switch, and hence eliminate dull and monotonous impression during turning on a conventional switch.

Abstract: A belt gear-positioning device to be assembled on gear(s) includes positioning rod(s), securing fixture(s), wing nut(s) and positioning strip(s). By turning and adjusting the positioning rod(s), the securing fixture(s) can be respectively engaged tightly in the spoke spaces of the gear(s) for securing the gear(s), avoiding damaging the surfaces of the teeth of the gear(s) and making it possible to safely carry out timing belt removal and/or replacement.
