Removable pin 15 is adopted to be fastened on hole seat 17 on chassis 16 and sliding seat 1, make sliding seat 1 can rotate certain angle around removable pin 15 on chassis 16, reach and to ensure to be arranged on column body in sliding seat 1 when chassis 16 is arranged on the ground of inclination and horizontal plane is kept at an angle and the top of gardens special-purpose ladder is ridden on branch or trunk.

In order to make the assembling of gardens pruning special-purpose ladder quick, chassis 16, hole seat 17, removable pin 15 and sliding seat 1 are the parts of entirety or the dispersion fitted together.

In order to can the locking inner conical surface 11 of working good and male cone (strobilus masculinus) 10 not loosen, described locking hole 5, lock pin 6, force bearing disk 7, locking spring 8 and annular lock groove 9 form the locked inner conical surface 11 of working good of locking system and male cone (strobilus masculinus) 10.

In order to reduce costs and alleviate the weight of gardens pruning special-purpose ladder, the column body of described gardens pruning special-purpose ladder adopts the mode of connecting to be combined into single with sliding seat 1 and column body with column body and independently supports, and sliding seat 1 and column body are hollow body or solid; Column body is individual layer or multilayer in the combination of ladder, and chassis 16 and sliding seat 1 are individual layers in the combination of ladder.

In order in use can Rapid Combination and facilitate pin to step on, described column body be combined into global facility with foot-operated 13, can assembly fast when being beneficial to use; Described foot-operated 13 fixing employing pin on column body are connected and fixed, and foot-operated 13 one end be merely able on column body to connector 3 are drawn, downward landing when pin is stepped down on foot-operated 13.

The assemble method of gardens pruning special-purpose ladder: during assembling, A, on the ground place fit together chassis 16, hole seat 17, removable pin 15 and sliding seat 1, chassis 16 on ground, sliding seat 1 is above, again the lower end of the column 2 having male cone (strobilus masculinus) 10 is inserted in the Inner taper hole 12 of sliding seat 1, under the effect of self gravitation, the male cone (strobilus masculinus) 10 of column 2 is naturally fitted with the inner conical surface 11 of sliding seat 1 and fixes, and the gravity depressed from column 2 is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted, insert in the process of Inner taper hole 12 at the male cone (strobilus masculinus) 10 of column 2, during inner conical surface 11 position that locking head enters into, inclined-plane on inner conical surface 11 oblique promotion locking head makes locking head compress locking spring 8 and outside oblique yielding, when the male cone (strobilus masculinus) 10 of column 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of sliding seat 1, locking head just in time enters the position of annular lock groove 9 after slipping over the inner conical surface 11 above annular lock groove 9 smoothly, locking head enters in annular lock groove 9 under the powered of locking spring 8, to coordinate with the inner conical surface 11 of fitting with the locking face of the annular lock groove 9 of V-arrangement and male cone (strobilus masculinus) 10 is locked can not retreat by facing directly of locking head, complete the fixing and locking of column body and sliding seat 1.One end of male cone (strobilus masculinus) 10 is again had by another root post body to insert in the Inner taper hole 12 of connector 3 in Inner taper hole 12 in B, connector 3 on column body, under the effect of self gravitation, the male cone (strobilus masculinus) 10 of column 2 is naturally fitted with the inner conical surface 11 of connector 3 and fixes, and the gravity depressed from column body is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted, insert in the process of Inner taper hole 12 at the male cone (strobilus masculinus) 10 of column 2, during inner conical surface 11 position that locking head enters into, inclined-plane on inner conical surface 11 oblique promotion locking head makes locking head compress locking spring 8 and outside oblique yielding, when the male cone (strobilus masculinus) 10 of column 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of connector 3, locking head just in time enters the position of annular lock groove 9 after slipping over the inner conical surface 11 above annular lock groove 9 smoothly, locking head enters in annular lock groove 9 under the powered of locking spring 8, to coordinate with the inner conical surface 11 of fitting with the locking face of the annular lock groove 9 of V-arrangement and male cone (strobilus masculinus) 10 is locked can not retreat by facing directly of locking head, when the column body composition of C, employing multilayer prunes gardens special-purpose ladder, repeat the male cone (strobilus masculinus) 10 again inserting column 2 in the Inner taper hole 12 of column body upper end of step B, afterwards, the male cone (strobilus masculinus) 10 of column body can insert in the Inner taper hole 12 of a root post body below by Using such method again, completes being connected and fixed and locking between column body and column body.The assembling of column body and sliding seat 1 and column body and column body is very convenient, just can complete without any need for instrument.

The method for dismounting of gardens pruning special-purpose ladder: during the column body of dismountable, pull the pin handle of lock pin 6, after the locking head of lock pin 6 front end exits the annular lock groove 9 on inner conical surface 11, column body upwards one is drawn or one lifts and automatically will separate with the Inner taper hole 12 in the connector 3 of a root post body below, and the male cone (strobilus masculinus) 10 of column body will separate automatically with the Inner taper hole 12 of the connector 3 of a root post body below.During the column body that dismounting sliding seat 1 is fixed, pull the pin handle of lock pin 6, after the locking head of lock pin 6 front end exits the annular lock groove 9 on male cone (strobilus masculinus) 10, column body upwards one is drawn or one lifts and automatically will separate with the Inner taper hole 12 of sliding seat 1, and column body will separate automatically with sliding seat 1.The dismounting of column body and sliding seat 1 and column body and column body is very convenient, just can complete without any need for instrument.

Gardener is when arranging gardens, run into when having trees to need pollard, first the chassis 16 fitted together, hole seat 17, removable pin 15 and sliding seat 1 are placed on the ground, after sliding seat 1 is plugged the first root post body, again another root post body insertion root post body below, when so repeatedly insertion column body reaches the height of needs, column body above the sliding seat 1 pulling gardens special-purpose ladder, makes column body rotate around removable pin 15 and lean against on trunk or branch by the top of gardens special-purpose ladder; Afterwards, pin steps down on foot-operated 13 on column body and climbs up, and prunes branch at suitable height.When having pruned descending stair after branch, pin has stepped down on foot-operated 13 and has down climbed, very convenient.
