Abstract
Description
Technical Field
[0001] This utility model relates to the field of antistatic brush technology, and in particular to antistatic brushes. Background Technology
[0002] An antistatic brush is a tool used to eliminate static electricity. It mainly consists of bristles and a handle. The bristles of an antistatic brush are mainly made of materials such as polyester filaments, nylon, or polyester fibers. These materials have high resistance characteristics and easily generate and retain static charge when rubbed.
[0003] The inventor discovered during daily use of anti-static brushes that the bristles of a typical brush are fixed to the surface of the handle, which leads to bristle shedding over time. This results in the brush being less effective at removing static electricity, thus reducing its anti-static performance and causing problems. Utility Model Content

[0006] The effect achieved by the above components is that, under the action of the locking rod, the T-shaped block is fixed inside the T-shaped groove, thereby achieving the function of fixation.
[0007] Preferably, the inner wall of the T-shaped groove is provided with a circular groove, and a ball bearing is rotatably connected inside the circular groove.
[0008] The effect achieved by the above components is that, under the action of the ball bearings, the T-shaped block can slide smoothly inside the T-shaped groove, thereby replacing the bristles.
[0009] Preferably, a first spring is sleeved on the surface of the clamp rod, and the two ends of the first spring are fixedly connected to one end of the clamp rod on the side of the brush.
[0010] The effect achieved by the above components is that, under the action of the first spring, the locking rod is inserted into the groove on the surface of the T-block to fix the T-block.
[0011] Preferably, a pad, which is a rubber plate, is fixedly connected to the inner wall of the T-shaped groove.
[0012] The aforementioned components achieve the following effects: The pad prevents the T-block from directly contacting the inner wall of the T-slot, avoiding damage caused by rigid contact. When brush bristles need to be replaced, the locking rod is pulled outwards, allowing the T-block to slide out of the T-slot. A new T-block is then inserted into the T-slot, where the ball bearings facilitate smooth sliding, allowing the brush bristles to be replaced. The pad prevents direct contact between the T-block and the inner wall of the T-slot, again avoiding damage caused by rigid contact. The first spring causes the locking rod to self-lock into the groove on the surface of the T-block, securing it and thus achieving the purpose of replacing the brush bristles.
[0013] Preferably, the side of the brush is provided with a folding device, the folding device includes a hinge fixedly connected to the side of the brush, a fixing plate fixedly connected to the side of the brush, a fixing rod inserted into the surface of the fixing plate, and a groove is opened on the side of another brush, one end of the fixing rod is inserted into the inside of the groove.
[0014] The effects achieved by the above components are as follows: the hinge allows the brush to be folded, thus achieving the folding effect; the fixing plate and fixing rod allow the brush to be extended and fixed.
[0015] Preferably, a retaining ring is fixedly connected to the surface of the fixing rod, and the retaining ring is a rubber ring.
[0016] The effect achieved by the above components is that, under the action of the retaining ring, the fixing rod will not slip out of the groove, thereby achieving the function of limiting the position.
[0017] Preferably, a rectangular plate is fixedly connected to the side of the brush, a locking rod is inserted into the side of the rectangular plate, and a slot is opened on the side of the other brush, with one end of the locking rod inserted into the slot.

[0019] Preferably, a second spring is sleeved on the surface of the locking rod, and the two ends of the second spring are respectively fixedly connected to one end of the locking rod on the side of the rectangular plate.
[0020] The aforementioned components achieve the following effects: Under the action of the second spring, the locking rod can be inserted into the slot in a self-locking manner, thus achieving a fixing effect. When the brush needs to be extended, the locking rod is pulled out from the slot, and the brush is rotated via the hinge to extend it. Once the brush is on the same plane, the fixing rod is inserted into the groove. Under the action of the retaining ring, the fixing rod will not slip out of the groove, thus achieving a limiting effect and extending the brush. When extension is not needed, the brush is folded via the hinge. Under the action of the locking rod, the folded brush is fixed, thus achieving a fixing effect. Under the action of the second spring, the locking rod can be inserted into the slot in a self-locking manner, thus achieving a fixing effect and folding.
