Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

As shown in Fig. 1 and Fig. 2, a push cylinder dismounting tool includes two hinged pliers 1, the pliers 1 include a head end 101 and a handle end 102, the two ends of the pliers 1 The thickness of 101 is 7mm, to ensure that the two ends 101 have enough room for movement inside the instrument, so as to facilitate the clamping of the push cylinder; each has a half hole 103, and the half hole 103 includes an upper hypotenuse 106 connected sequentially from top to bottom , vertical side 107 and bottom side 108, and the included angle between upper hypotenuse 106, vertical side 107 and bottom side 108 is 60 °, the side length of upper hypotenuse 106 and vertical side 107 is identical, bottom side 108 Shorter than the upper hypotenuse 106 and the vertical side 107, when the two pliers 1 are closed, the half holes 103 at the ends 101 form regular hexagonal jaws 104, and the regular hexagonal jaws 104 are pushed against the outer wall of the cylinder The shape matches completely, the top edge of the regular hexagonal jaw 104 is an opening 105, the side length of the opening 105 is equal to the upper hypotenuse 106 and the vertical edge 107, and the bottom edge 108 of the half hole 103 of the two ends 101 plus two The length of the interval between the base 108 is equal to the upper hypotenuse 106 and the vertical edge 107, thereby forming a regular hexagonal jaw 104; the pliers 1 can be sleeved on the cylinder from the opening 105; The inner sides of the two handle ends 102 are respectively provided with limit pins 2, and the limit pins 2 of the two handle ends 102 offset each other. There is a certain space between them, and this space avoids pinching hands during use; the two handle ends 102 of the pliers body 1 are provided with rubber sleeves 3, and the rubber sleeves 3 are protective tubes of polyvinyl chloride, which increases friction on the one hand and facilitates The operator holds it, and on the other hand, avoids direct metal contact with the control circuit and hydraulic pipeline, thereby avoiding damage to the internal circuit and pipeline of the instrument; the two handle ends 102 of the caliper body 1 are elongated pliers handles, which can be easily Bypass the control circuit and hydraulic pipeline inside the instrument to avoid accidental damage to the instrument by tools during disassembly and assembly.
