[0005] The technical solution adopted by the utility model to solve the above technical problem is: an integrated structure of a cylinder sheath, including an air chamber, a ram, a guiding sleeve, a thrust ring and an auxiliary ram. The ram is slidably arranged in the air chamber. A thrust ring is sleeved on the front end of the auxiliary ram, and a guiding sleeve is sleeved on the rear end of the auxiliary ram. The guiding sleeve is embedded in the air chamber. The ram can push the auxiliary ram. The integrated structure of a cylinder sheath further includes a connecting cylinder, and the connecting cylinder is connected to the end of the air chamber and is located outside the thrust ring.

[0006] A further preferred solution of the utility model is that a hole groove is formed on the side wall of the connecting cylinder, and a through limiting groove is formed on the side wall of the air chamber. The hole groove and the limiting groove can coincide with each other.

[0007] A further preferred solution of the utility model is that it further includes steel balls. The steel balls are arranged between the hole groove and the limiting groove, and the steel balls can fixedly connect the connecting cylinder and the air chamber.

[0008] A further preferred solution of the utility model is that it further includes a sealing gasket. The sealing gasket is arranged at the end of the air chamber, specifically at the connection between the air chamber and the connecting cylinder.

[0009] A further preferred solution of the utility model is that it further includes a top cover. The top cover closes the limiting groove by a clamping method.

[0010] A further preferred solution of the utility model is that it further includes a protective sleeve. The protective sleeve is sleeved outside the connecting cylinder.

[0011] A further preferred solution of the utility model is that a constant pressure hole is formed at the end of the connecting cylinder.

[0012] Compared with the prior art, the advantages of the present utility model are as follows: The secondary hammer is limited by the guiding sleeve and the thrust ring, and then the connecting cylinder is fixed by the coincidence of the hole groove and the limiting groove and the limitation of the steel ball, so as to press and fix the guiding sleeve and the thrust ring. The impact hammer drives the secondary hammer. The structure of this device is concise but has strong stability, improves the adaptability to different electric specifications, reduces the volume and also lightens the weight.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The preferred embodiments of the present utility model will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present utility model.

[0020] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0021] This embodiment mainly elaborates on the structure of the air cylinder, as follows: A structure in which the air cylinder and the protective sleeve are integrated, as Figures 1 - 4As shown in the figure, it includes an air chamber 5, a ram 6, a guide sleeve 1, a thrust ring 3 and a sub-hammer 2. The ram 6 is slidably arranged in the air chamber 5. A thrust ring 3 is sleeved on the front end of the sub-hammer 2, and a guide sleeve 1 is sleeved on the rear end of the sub-hammer 2. The guide sleeve 1 is embedded in the air chamber 5. The ram 6 can push the sub-hammer 2. It also includes a connecting cylinder 4, and the connecting cylinder 4 is connected to the end of the air chamber 5 and is located outside the thrust ring 3.

[0022] As Figure 3 shown, a hole groove 7 is provided on the side wall of the connecting cylinder 4, and a through limiting groove 8 is provided on the side wall of the air chamber 5. The hole groove 7 and the limiting groove 8 can coincide with each other. It also includes a steel ball 9, and the steel ball 9 is arranged between the hole groove 7 and the limiting groove 8. The steel ball 9 can fixedly connect the connecting cylinder 4 and the air chamber 5.

[0023] As Figure 4 shown, it also includes a gasket 10, and the gasket 10 is arranged at the end of the air chamber 5, specifically at the connection between the air chamber 5 and the connecting cylinder 4. The setting of the gasket 10 can reduce the intrusion of sundries into the air chamber 5.

[0024] As Figure 4 shown, it also includes a top cover 11, and the top cover 11 closes the limiting groove 8 by means of clamping. The top cover 11 is used to seal the limiting groove 8.

A constant pressure hole 13 is provided at the end of the connecting cylinder 4 to facilitate the opening and closing of the protective sleeve 12.

[0026] Working principle: The sub-hammer 2 is limited and slides in the sliding space composed of the thrust ring 3 and the guide sleeve 1. The ram 6 in the air chamber 5 impacts and drives the sub-hammer 2. An annular fixing ring is arranged outside the guide sleeve 1, and this fixing ring can limit the guide sleeve 1 at the corresponding position in the air chamber 5. Insert the connecting cylinder 4 into the front end of the air chamber 5 so that the hole groove 7 and the limiting groove 8 coincide. A steel ball 9 is arranged between the hole groove 7 and the limiting groove 8 to fix the connecting cylinder 4. At this time, the connecting cylinder 4 can press and fix the fixing ring part of the guide sleeve 1 to fix the guide sleeve 1. At the same time, the inner groove of the connecting cylinder 4 squeezes and fixes the thrust ring 3, thereby fixing the thrust ring 3 and the guide sleeve 1. A constant pressure hole 13 is provided at the front end of the connecting cylinder 4, and the protective sleeve 12 can be sleeved outside the connecting cylinder 4 to physically protect it.
