Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] Such as figure 1 As shown, the machine head resilience device of the present invention comprises a body 2, a machine head 1 and a clip spring 6, the body 2 is provided with a body support 3, and a positioning pin 4 is installed on the body support 3; There is a sleeve 5 for placing the compression spring 6, the top of the compression spring 6 is in contact with the upper inner wall of the sleeve 5, the top of the compression spring 6 is fixed in the sleeve 5 by a fixing device, and the bottom of the compression spring 6 is provided with a pressure The spring holder 7, by extruding the stage clip 6, makes the bottom of the stage clip holder 7 and the contact surface of the positioning pin 4 be in full contact, also known as full contact. Wherein, the fixing device includes a pressing plate 8 and a hexagonal screw 9 for fixing the pressing plate 8 . The compress...

The invention discloses a machine head rebounding device which comprises a machine body, a machine head and a compressed spring. The machine body is provided with a machine body support, and a locating pin is mounted on the machine body support. The machine head is provided with a sleeve where the compressed spring can be placed, and the top of the compressed spring makes contact with the inner wall of the upper portion of the sleeve and is fixed in the sleeve through a fixing device. The bottom of the compressed spring is provided with a compressed spring fixing base, and the bottom of the compressed spring fixing base can make full contact with the contact surface of the locating pin through extrusion on the compressed spring. According to the machine head rebounding device, since a common torsion spring is replaced by the compressed spring to rebound the machine head, and the structure of the machine body and the structure of the machine head are adaptively improved, the machine head can be rebounded in place more easily, that is the compressed spring can rebound more easily than the torsion spring do when the machine head is pressed downward to a certain position and external force is removed by loosening both hands.
Description
technical field [0001] The invention relates to an electric cutting tool, in particular to a rebound device of the electric cutting tool. Background technique [0002] Currently, electric cutting tools are widely used in the field of machining and manufacturing. Miter saws are one of the most common power cutting tools. The miter saw includes a machine head and a body. During use, when the workpiece needs to be cut, as long as the machine head is pressed down, the saw blade can be driven to cut the workpiece; after cutting, the machine head rebounds. Miter saws in the prior art generally use torsion springs to make the machine head rebound, and torsion springs are springs that rely on their torsion elasticity to generate friction to transmit power or motion. Therefore, using a torsion spring to make the machine head rebound usually requires the help of external force, which brings inconvenience to the operation.
