DETAILED DESCRIPTION

[0018] To make the technical problems, technical solutions and advantages of the utility model clearer, specific embodiments will be described in detail below with reference to the drawings.

[0019] As shown in the accompanying Figure 1 to the accompanying Figure 3 The embodiment of the utility model provides a kind of portable valve accessory repair tool, including L-shaped support 1, L-shaped support 1 side is provided with telescopic rotating assembly 2, the lower side of telescopic rotating assembly 2 is provided with fixed clamping assembly 3, and the outer surface of the side of L-shaped support 1 is fixedly installed with handle 4;

[0020] Telescopic rotating assembly 2 includes mounting block one 21, and the upper side outer surface of mounting block one 21 is fixedly installed with motor 22, and the output end outer surface of motor 22 is fixedly installed with gear 23, and the side of gear 23 is provided with hollow column 24, and the inner wall of hollow column 24 is slidably installed with connecting column 25, and the top of connecting column 25 is fixedly installed with pull ring 26, and the outer wall of connecting column 25 is fixedly sleeved with limit chuck 27, and the upper side outer surface of limit chuck 27 is fixedly connected with spring 28.

[0021] Among them, hollow column 24 is rotatably connected to the inner wall of mounting block one 21, limit chuck 27 slides on the inner wall of hollow column 24, and spring 28 is attached to the inner cavity surface of hollow column 24;

[0022] By starting motor 22 to drive connecting column 25 to rotate, the rotation of mounting block two 31 is realized, so that the automatic disassembly of bolt and nut is realized, the disassembly efficiency is improved, the workload and labor intensity of maintenance personnel are reduced, and the maintenance efficiency of valve accessory is greatly improved to a certain extent.

[0023] Among them, fixed clamping assembly 3 includes mounting block two 31, and the inner wall of mounting block two 31 is rotatably connected with forward and reverse screw rod 32, and the outer surface of forward and reverse screw rod 32 is symmetrically connected with connecting plate 33, and the outer surface of the side of connecting plate 33 is fixedly installed with clamping plate 34, and the outer surface of one end of forward and reverse screw rod 32 is fixedly installed with knob 35, and connecting plate 33 slides on the inner wall of mounting block two 31, and forward and reverse screw rod 32 slides on the outer surface of the side of mounting block two 31, and mounting block two 31 is fixedly installed at the bottom end of connecting column 25;

[0024] By rotating the knob 35, the two clamping plates 34 move relative to each other and clamp the sides of the bolt and nut, thus achieving relative fixation of the bolt and nut.
