At least one of the radially upper side and the radially lower side is provided with a sleeve perpendicular to the handle, and the cross-section of the inner hole of the sleeve is square or regular hexagon in the length direction of the handle.

The beneficial effects of the above technical solutions are as follows: the integrated wrench used for the installation and disassembly of the gas valve and gas meter of the present invention overcomes the defect of using a variety of different tools in one process, and the handle, the static die and the movable die form an adjustable wrench, and the casing. The socket set on it can form a socket wrench, the inner hole of the socket can be matched with the bolts and nuts on the oxygen cylinder and the acetylene cylinder, and the position of the sleeve can be adjusted on the handle, so as to adjust the length of the whole wrench and improve the wrench. of use torque. The utility model integrates the wrenches used for gas cutting and gas welding, has complete functions, and effectively solves the problems of inconvenient use and carrying and unsuitable for actual production requirements of the existing methods for operating gas cylinders. During electric welding operation and maintenance, only one integrated wrench of the utility model for installation and disassembly of the gas valve and gas meter can be carried, so that the construction cost is greatly reduced and the production efficiency is greatly improved.

Further, both the radially upper side and the radially lower side of the end of the sleeve away from the static die are provided with a sleeve perpendicular to the handle.

Beneficial effect: when the operator installs and disassembles the gas valve and gas meter, he can choose any one of the sleeves, and the other one can be used as a spare.

Further, the shapes of the inner holes of the sleeves disposed on the radially upper side and the radially lower side of the end of the sleeve away from the static die are different.

Beneficial effects: the bolts and nuts of different shapes can be screwed, and the applicable scope of the whole integrated wrench is improved.

Further, the inner holes of the sleeve disposed on the radially upper side and the radially lower side of the end of the sleeve away from the static die have the same shape and different sizes.

Beneficial effects: the bolts and nuts of the same shape and different sizes can be screwed, avoiding the use of additional wrenches, and realizing multi-purpose integration.

Further, magnets are provided on opposite sides of the static die and the movable die.

Beneficial effects: The magnet can attract the bolts and nuts to be installed or disassembled, prevent them from falling, and reduce the possibility of losing the bolts or nuts.

Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, Figure 2 and Figure 3, the integrated wrench used for the installation and removal of the gas valve and gas meter includes a handle 1 and a static die 2 integrally formed at the end of the handle 1. The handle 1 is also on the same end of the static die 2. There is a movable die 3 that can approach and move away from the static die 2 , and a movable jaw 8 is formed between the movable die 3 and the static die 2 . The handle 1 is covered with a sleeve 5 that can move along the length direction of the handle 1, the handle 1 is provided with a long hole 7 extending along the length direction of the handle 1, the sleeve 5 is adapted to the shape of the handle body of the handle 1, and the sleeve The pipe 5 is provided with four fixing holes 6 spaced along the length direction of the handle 1 at positions corresponding to the long holes 7 . The sleeve 5 is connected with the handle by two bolts 9 and two nuts 10. In this embodiment, the sleeve position of the sleeve 5 on the handle 1 can be adjusted, and then the use length of the entire integrated wrench can be adjusted. 7 Able to reduce the weight of the entire wrench for easy portability. In the initial state, the sleeve 5 is completely sleeved on the handle 1, and the sleeve 5 and the handle 1 can be firmly fixed together only by piercing bolts at the positions of the first fixing hole and the fourth fixing hole. When the length needs to be adjusted, unscrew the two nuts 10 from the corresponding bolts 9, take out the two bolts 9, then move the sleeve 5 along the length of the handle 1, and finally thread the two bolts 9 on the first One and the second fixing hole, and tighten the two nuts.

A sleeve 4 perpendicular to the handle 1 is welded on the radially upper side and the radially lower side of the end of the sleeve 5 away from the static die 2 . The diameter of one of the square holes is 10mm, which is used for the disassembly and assembly of the gas valve of the acetylene cylinder; the diameter of the other square hole is 8mm, which is used for the disassembly and assembly of the gas valve of the oxygen cylinder.

In this embodiment, the handle 1, the static die 2 and the movable die 3 form an adjustable wrench, the sleeve 5 and the sleeve 4 provided on it can form a socket wrench, and the inner hole of the sleeve can be connected with the oxygen cylinder and acetylene gas. The bolts and nuts on the bottle are matched, and the position of the sleeve 5 can be adjusted on the handle, so as to adjust the length of the entire wrench and improve the use torque of the wrench. In order to avoid the nuts or bolts to be installed and removed from falling on the ground and being lost, in this embodiment, magnets 11 are provided on opposite sides of the static die and the movable die.
