Abstract
The utility model discloses a lawn moaner cutter fastening bolt, which comprises a bolt body (4) and an insulation separator (3), wherein the end of the bolt (4) is arranged in the insulation separator (3); the top of the insulation separator (3) is provided with a protruding fastener (1); the appearance of the fastener (1) is the hexagon or the quadrangle structure; the fastening surface of the fastener (1) is embedded with a metal protection sleeve (2). When above structure is adopted, the metal protection sleeve (2) realized the objective that after the fastener (1) is used for a long time, the edges and corners of the outer outline will not be frayed by friction or collision. The bolt has the advantages of simple and reasonable structure, fraying resistance, long service life, etc., thereby basically solving the problem that the lawn moaner cutter is hard to be disassembled or replaced.
Description
Technical field
The utility model relates to a kind of clamping bolt, particularly a kind of clamping bolt of fixedly mower blade.
Background technique
At present, most of mowing machines all are to use a nonstandard blade clamping bolt that blade is fixedly connected on the machine; Because this bolt directly is fixed on the motor output shaft, and the motor that uses generally adopts the substance insulation system, double insulation in order to ensure electric tool, so this bolt unique vitals that can in double insulation, play superinsulation that when playing fastening blade effect, also is mowing machine; Therefore just formed a nonstandard body of bolt structure has been set on the insulating spacer; Insulating spacer generally adopts working of plastics, adds generally by the injection moulding mode the nonstandard body of bolt to be thrown in the working of plastics man-hour, becomes fastener in its top design, fastener is generally structures such as outer-hexagonal, four jiaos, simultaneously be furnished with a spanner at random, be used for demounting bolt, change blade; Yet extensibility of structure has Just because of this gone out a problem, is exactly after long-time the use, and the fastener outer-hexagonal of blade clamping bolt or four jiaos can be because of frictions, collide with and wear and tear, and finally cause blade to dismantle or to change.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing Lawn mower blade fastening bolt exists, the utility model provide a kind of simple and reasonable, can conform to the insulation conditional request, can prevent the Lawn mower blade fastening bolt that weares and teares again.The technological scheme that its technical problem that solves the utility model adopts, it comprises the body of bolt, insulating spacer, the end of the body of bolt is arranged in the insulating spacer, and the insulating spacer top is provided with the fastener to outer lug, is inlaid with protective metal shell spare on fastening of described fastener.
For the ease of using operation, the profile of described fastener is hexagon or tetragonal structure.
After adopting said structure, inlay anti abrasive protective metal shell spare on the fastener of insulating spacer, make fastener after long-time the use, the corner angle of its external frame can be because of not rubbing, colliding with and wear and tear; Have advantages such as simple and reasonable, wear-resistant, long service life, solved the problem that mower blade can't be dismantled or change basically.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Figure 1, specific embodiments for the utility model Lawn mower blade fastening bolt, it comprises the body of bolt 4, insulating spacer 3, the end of the body of bolt 4 is arranged in the insulating spacer 3, insulating spacer 3 tops are provided with the fastener 1 to outer lug, the profile of fastener 1 is hexagon or tetragonal structure, is inlaid with protective metal shell spare 2 on fastening of described fastener 1.When the utility model uses, since on fastening of fastener 1 protective metal shell spare 2 is arranged, therefore, after the long-time use of mowing machine, the Ling Jiao of insulating spacer 3 external frames not can because of the friction, collide with and wear and tear, thereby solved the problem that blade can't be dismantled or change.
Above-mentioned the utility model is described, but obviously also has the change of many equivalent technologies to one skilled in the art, the change of being done under the precondition that does not depart from the claim flesh and blood still belongs to the rights protection scope of this patent.
Claims (2)
1, a kind of Lawn mower blade fastening bolt, comprise the body of bolt (4), insulating spacer (3), the end of the body of bolt (4) is arranged in the insulating spacer (3), insulating spacer (3) top is provided with the fastener (1) to outer lug, it is characterized in that: be inlaid with protective metal shell spare (2) on fastening of described fastener (1).
2, Lawn mower blade fastening bolt according to claim 1 is characterized in that: the profile of described fastener (1) is hexagon or tetragonal structure.
