In order to solve the poor problem of gland fastening tool performance among the prior art, this application provides a formula gland list eave tile spanner cut straightly.

As shown in fig. 1, the in-line gland single hook wrench in the present application includes a main body 10, a handle 20, and a fastening hook 30. The main body part 10 is arc-shaped, the main body part 10 comprises a main body section 11, a first extension section 12 and a second extension section 13, and the first extension section 12 and the second extension section 13 respectively extend out in opposite directions along the thickness direction of the main body section 11; one end of the handle 20 is connected with the main body part 10, and the other end of the handle 20 extends along one side of the direction far away from the center of the main body part 10; the fastening hook 30 and the handle 20 are respectively disposed at both ends of the main body section 11, and the fastening hook 30 extends in a direction close to the center of the main body section 10.

When the straight-inserting type gland single-hook wrench with the structure is used, an operator can control the main body part 10 to be close to a gland to be fastened through the handle 20, and the fastening hooks 30 are respectively aligned with the slots of the gland. When the fastening hooks 30 are all inserted into the slots of the gland, the main body section 11 of the main body 10 is attached to the gland. At this time, the handle 20 can drive the main body 10 and the fastening hooks 30 to rotate, so as to fasten the gland. Moreover, the straight-inserting type gland single-hook wrench in the application can effectively prevent the rotation of the gland from slipping in the process and can improve the working efficiency of operators. Also, since the main body part 10 further includes the first extension 12 and the second extension 13, stability of the main body part 10 may be ensured in the process of fastening the gland.

It should be noted that the straight-insertion type gland single-hook wrench in the application can be used for not only fastening the gland, but also detaching the gland.

Specifically, the arc of the body 10 is 45 degrees or more and 135 degrees or less. By such an arrangement, not only can the main body 10 and the gland have a sufficient contact area, but also the plurality of fastening hooks 30 can be inserted into the insertion grooves of the gland more easily.

In one particular embodiment of the present application, the arc of the body portion 10 is 90 degrees.

It should be noted that, since a plurality of pressing covers are generally provided on the plunger pump, and the interval between the pressing covers is small, when the pressing covers are fastened, after the fastening hook 30 rotates by a certain angle, the fastening hook 30 needs to be pulled out from the insertion slot and inserted into the insertion slot again after the position is adjusted.

Optionally, an included angle between a line connecting two sides of the fastening hook 30 to the center of the main body 10 is greater than 20 degrees and less than 40 degrees. The purpose of this arrangement is mainly to ensure that the fastening hook 30 can be fitted into the slot of the gland, and to increase the contact area between the fastening hook 30 and the slot as much as possible.

Specifically, the first extension 12 and the second extension 13 are both disposed on a side close to the center of the main body portion 10. By so arranging, the first extension 12 and the second extension 13 can be effectively prevented from colliding with other glands. In addition, the arrangement ensures that the force of the main body 10 can be concentrated on the contact part with the gland.

Specifically, a side of the first extension section 12 away from the fastening hook 30 and a side of the second extension section 13 away from the fastening hook 30 are respectively provided with a latch section 14, and the latch section 14 is located on a surface of the first extension section 12 and the second extension section 13 facing a circle center. Through setting up latch section 14, can increase the frictional force between main part 10 and the gland effectively to can prevent effectively that the relative slip from appearing between the in-process formula gland list eave tile spanner of fastening gland and the gland.

Specifically, the first extension 12 and the second extension 13 have an arc-shaped plate-like structure. By such an arrangement, the stability of the main body portion 10 can be further enhanced, thereby ensuring a stable fit of the main body segment 11 and the gland.

Specifically, the surface of the fastening hook 30 has a carburized layer. Through such an arrangement, not only the strength of the surface of the fastening hook 30 can be ensured, but also the fastening hook 30 can be more easily pulled out from the slot. Thereby reducing the friction between the fastening hook head 30 and the gland slot, reducing the friction between the fastening hook head 30 and the gland, and prolonging the service life of the fastening hook head 30 and the gland.

Optionally, the thickness is the same throughout the body section 11. By this arrangement, the body segment 11 can be effectively prevented from deflecting during tightening of the gland.

Optionally, the first extension 12 and the second extension 13 are symmetrically arranged with respect to the main body segment 11. By such an arrangement, the main body 10 is further effectively ensured not to be easily deflected and shaken during the rotation.

Optionally, the first extension 12 and the second extension 13 are perpendicular to the main body segment 11, respectively. By this arrangement, collision between the first and

second extensions

12 and 13 and the gland can be effectively avoided.

Optionally, the side of the handle 20 remote from the body portion 10 is provided with anti-slip threads.

Optionally, the side of the handle 20 remote from the main body 10 is provided with an anti-slip cover.

Through setting up like this, can play anti-skidding effect through anti-skidding screw thread and antiskid cover to guarantee operating personnel's the sense of gripping and reduce and skid.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:

1. the problem that the using part of a filler gland fastening tool is stable in the prior art is effectively solved;

2. the problem that the number of supporting points of a gland fastening tool is small is also solved;

3. the problem that the gland fastening tool is easy to slip when in use is solved;
