Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electric hammers, in particular to a portable electric hammer. BACKGROUND

[0002] An electric hammer is a high-efficiency impact type electric tool driven by electric energy, which is widely used in the fields of construction, decoration, mining, etc., and is mainly used for drilling holes or breaking hard materials such as concrete, stone and brick walls. The core structure of the electric hammer is composed of an electric motor, a transmission mechanism, a cylinder piston system and a drill bit. The electric energy is converted into high-frequency impact force through mechanical transmission, and the high-frequency impact force is combined with rotary motion to realize efficient penetration.

[0003] Compared with a traditional electric drill, the electric hammer adopts a pneumatic impact principle. During operation, the internal piston reciprocates in the cylinder to generate continuous impact force, so that the drill bit can produce thousands of impacts per minute (usually 4000-6000 times per minute), and the impact energy can reach 2-10 joules. This design greatly improves the efficiency of hard material processing, and the operation speed is 3-5 times faster than that of an ordinary electric drill, and can effectively reduce the physical exertion of the operator.

[0004] Modern electric hammers are equipped with electronic speed regulation, overload protection and damping systems, and some models support multi-mode switching such as "only rotation", "rotation + impact" and "flat chisel". They can adapt to various drill bits and chisels. Its application scenarios cover the opening of concrete structures, pipeline laying, tile removal and other engineering links, and it has become an indispensable mechanized tool in the construction industry. When using, safety glasses, dust masks and regular maintenance of lubricated parts are required to prolong the service life.

[0005] The electric hammer on the market, such as the one disclosed in CN114248238A, includes a gear box, a quick chuck connected to the front end of the gear box, a handle structure connected to the rear end of the gear box, a sub-handle mounted on the front part of the gear box, and a motor housing located below the rear part of the gear box. The bottom surface of the rear part of the gear box is connected to the motor housing through an intermediate cover. The handle structure includes a handle main body and a handle rear cover, which are connected by a screw. The rear end of the motor housing is connected to the bottom of the handle main body.

[0006] According to the related technology in the above, the inventor finds that the existing electric hammer can only be held by two hands when working, which leads to unstable positioning of the personnel when the impact force is too large. CONTENT OF THE UTILITY MODEL

[0007] In order to solve the above technical problems, the application provides a portable electric hammer which has the advantages of ensuring stable work and being easy to carry.

[0008] In order to achieve the above purpose, the technical scheme of the utility model is as follows:

[0011] The tail handle part is provided with a rear lifting ring, and the rear lifting ring is provided between the tail handle part and the rear fixing part.

[0012] The above technical scheme is realized, that is, after the money lifting ring is fixed at the gun head by the front fixing part, the rear lifting ring is fixed at the top of the tail handle part by the rear fixing part, and the person can hang a lifting belt between the front lifting ring and the rear lifting ring during use, so as to be carried on the back or hung at the neck for holding the tail handle part to ensure stability, thereby improving the convenience of use of the person.

[0013] As a preferred scheme of the present application, the front lifting ring comprises a lifting plate, the lifting plate is provided with a sleeving hole sleeved on the gun head part, and the lifting plate is provided with a waist-shaped lifting hole.

[0014] The above technical scheme is realized, so that after the lifting plate is sleeved on the gun head part, the hanging rope only needs to be hung on the waist-shaped lifting ring, and the setting of the waist-shaped lifting hole can enable the lifting rope to be adjusted along with the posture of the electric hammer, thereby ensuring the stability of hanging.

[0015] As a preferred scheme of the present application, the front fixing part comprises a positioning table arranged on the gun head part, the lifting plate is provided with a locking screw, and the locking screw is screwed and fixed on the positioning table.

[0016] The above technical scheme is realized, so that the lifting plate is locked and pressed and fixed on the positioning table by the locking screw, thereby realizing the detachable setting of the front lifting ring, so that when the front lifting ring is damaged, the front lifting ring can be replaced to ensure normal use of the person.

[0017] As a preferred scheme of the present application, the positioning table is provided with a positioning boss, and the lifting plate is provided with a positioning groove for clamping the positioning boss.

[0018] The above technical scheme is realized, so that during installation, only the positioning boss needs to be placed in the positioning groove, so as to ensure that the waist-shaped lifting hole is located above, thereby facilitating the installation of the locking screw.

[0019] As a preferred scheme of the present application, the rear lifting ring is a back-shaped ring, and the rear lifting ring is provided with a expansion joint.

[0020] As a preferred scheme of the present application, the rear fixing member comprises a U-shaped clamping groove provided inside the tail handle portion for clamping the rear lifting ring, and the tail handle portion top wall is provided with positioning holes communicated with both ends of the U-shaped clamping groove.

[0021] The rear lifting ring is clamped in the U-shaped clamping groove, and thus a part of the rear lifting ring is inserted in the U-shaped clamping groove and a part of the rear lifting ring extends out of the tail handle portion, thereby being used for hanging the lifting belt, and the elastic effect of the rear lifting ring makes the rear lifting ring abut against the U-shaped clamping groove, thereby ensuring stability.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. After the front lifting ring is fixed at the gun head by the front fixing member, the rear lifting ring is fixed at the top of the tail handle portion by the rear fixing member, and thus the lifting belt can be hung between the front lifting ring and the rear lifting ring when used by a person, so as to be used for carrying by the person or being hung at the neck for holding the tail handle portion to ensure stability, thereby improving the convenience of use by the person.
