Abstract
The utility model relates to an improvement on the structure of a self-locking device for a protective cover of an oblique cutting saw. An oblique cutting saw comprises a supporting frame, a head cover, a saw blade arranged in the head cover and an operating hand lever connected with the head cover, wherein a self-locking trigger is arranged between the head cover and the protective cover. The utility model has the advantages of reasonable structure, simple operation, favorable self-locking performance, easy maintenance, low cost, the realization of bulk production, etc.
Description
Technical field
The utility model relates to a kind of diagonal cutting saw, especially relates to a kind of to the isostructural improvement of diagonal cutting saw protective cover self-locking device.
Background technology
Diagonal cutting saw has very wide range of application as a kind of cutting tool, can be used to cut a lot of metals or nonmetallic materials.When the operator will pull the operation handle and cuts downwards, protective cover moved to the head-shield place automatically, thereby exposes blade cutting, cut efficient and conveniently, still, when the operator pulls described operation handle because of carelessness downwards, might bring adverse effect to the operator.
Summary of the invention
The utility model mainly is when solving existing in prior technology and pulling the operation handle downwards, and protective cover moves to the head-shield place automatically, thereby exposes blade cutting, makes the technical problem of using uneasy congruence.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: diagonal cutting saw protective cover self-locking device, described diagonal cutting saw comprises support, head-shield, is located at the saw blade in the head-shield, the operation handle that links to each other with head-shield, and is provided with the self-locking trigger between described head-shield and protective cover.When the operator will pull described operation handle and cuts downwards, described protective cover 11 was blocked by described self-locking trigger 2, and described protective cover 11 can't move upward and expose blade, and the complete machine head can't be pulled downwards and cut, and had improved the security of operation.
As preferably, described self-locking trigger one end be arranged on described operation handle around, the other end is near described head-shield, and extends to described protective cover is inboard.Help when not using diagonal cutting saw, effectively pinning described protective cover, improved the security of operation; Help operation simultaneously to described self-locking trigger.
As preferably, the nearly described operation handle end of described self-locking trigger is provided with Trigger shoe.Help the described self-locking trigger of handled easily, improve operator's feel simultaneously.
As preferably, described self-locking trigger becomes 7 fonts.Help operation and pin described protective cover.
As preferably, described self-locking trigger becomes zigzag, and described self-locking trigger passes described operation handle, and described self-locking trigger two ends are positioned at the both sides of described operation handle.The convenience that helps operating is pinned described protective cover simultaneously.
As preferably, described self-locking trigger be connected from lock connecting rod, describedly be connected with described head-shield from lock connecting rod.Help the twisting of described self-locking trigger.
As preferably, describedly be provided with spring from lock connecting rod and support seat, described spring support seat is provided with torsion spring; Describedly be provided with jump ring from lock connecting rod described self-locking trigger end far away.Help the twisting of described self-locking trigger, help resetting of described self-locking trigger simultaneously.
Therefore, the utlity model has rational in infrastructurely, simple to operate, self-locking property is good, maintenance easily, cost is low, can realize characteristics such as batch process.
Description of drawings
Accompanying drawing 1 is a kind of main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 is structural representations that head section P is in self-locking state in the utility model to the self-locking trigger;
Accompanying drawing 3 is the status architecture schematic diagrames when the head section blade cuts in the utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: diagonal cutting saw protective cover self-locking device, as shown in Figure 1, described diagonal cutting saw comprises support, head-shield, is located at the saw blade in the head-shield, the operation handle that links to each other with head-shield, be provided with self-locking trigger 2 between described head-shield 9 and the protective cover (11), described self-locking trigger 2 one ends be arranged on described operation handle 12 around, the approaching described head-shield 9 of the other end, and to described protective cover 11 inboard extensions.Described self-locking trigger 2 nearly described operation handle 12 ends are provided with Trigger shoe 6,2 one-tenth 7 fonts of described self-locking trigger, described self-locking trigger 2 is positioned at a side of described operation handle 12, described self-locking trigger 2 by screw 3 be connected from lock connecting rod 4, describedly be connected with described head-shield 9 by screw 7 from lock connecting rod 4, describedly be arranged between described head-shield 9 and the described operation handle 12 from lock connecting rod 4, describedly be provided with spring from lock connecting rod 4 and support seat 8, described spring support seat 8 is provided with torsion spring 5, described torsion spring 5 is against in the described head-shield 9, describedly is provided with jump ring 10 from lock connecting rod 4 described self-locking trigger 2 ends far away.
Embodiment 2: as Fig. 2 or shown in Figure 3, and 2 one-tenth zigzags of described self-locking trigger, described self-locking trigger 2 passes described operation handle 12, and described self-locking trigger 2 two ends are positioned at the both sides of described operation handle 12, and remaining is with embodiment 1.
The described trigger bar 4 of described self-locking trigger 2 usefulness is movably connected on the described head-shield 9, as described in Figure 2, when the operator will pull the cutting downwards of described operation handle 12 be, described protective cover 11 is blocked by described self-locking trigger 2, described protective cover 11 can't move upward and expose blade, the complete machine head can't be pulled downwards and cut, have only when the operator pulls the position of (to the direction of Fig. 2 arrow) described self-locking trigger 2 to Fig. 3, as shown in Figure 3, described protective cover 11 could be pulled downwards with head, expose blade cutting, when cutting finishes, head is got back to the position of Fig. 1, and described self-locking trigger 2 automatically resets under the effect of described torsion spring 5 and pins described protective cover 11.
